In this question it is asked that what should a matrix of 5 into 5 dimension should look like if the element a .i .i.
00:12
Is 0 for each i.
00:15
So first of all, we should know that we have a matrix of 5 by 5 order.
00:22
Then we can say that basically it should look like this way here.
00:31
That is a1, a12, a13, a14, a15, then it should have a21, a22, a23.
00:42
Wait a while i am going to change the shape here because we need more space.
00:52
So i had increased the shape here.
00:57
Now it should have a11, a12, a13, a14, a15.

In the first row in the second row a two one a two two two three a two four a two five in the third row a three one a three four a three five and in the fourth row a four one a four a four a four a four five in the fifth row a five one a five one a five two a five three a five four a five five five now it is being asked that we have to make aiii equals to 0.
01:39
It means that a11, a22, a33, a44 and a555...
